Definitions

  • the Applicant is nevertheless aware of a large number of filters that utilise an endless travelling cloth. These cloths are mostly supported by belts.
  • the philosophy of a filter is totally different from that of the present invention.
  • filters are intended to filter out solid particles that are in suspension in a liquid.
  • the intention is to remove all the solid particles.
  • the object is to separate the first solid component from the second solid component, with there being substantially more of the second solid component than there is of the first solid component, so that much more solid material passes through the apparatus than is removed by it.
  • the cloth 12 is a fabric that is woven from a suitable synthetic mono-filament material.
  • the material may be polypropylene, polyester or polyamide.
  • the cloth is woven to have apertures of a suitable size depending on the application for which it is intended.
  • the cloth is provided with apertures of about 250 microns in size.
